 In either case (1G or 2G) and for just about any input, you can also consider using a unity buffer to drive the ECU.  Such a device presents a low-load input for connecting the external sensor and then produces a higher drive output for connecting to the ECU's input. ​ The following schematic can be used to build this device. In either case (1G or 2G) and for just about any input, you can also consider using a unity buffer to drive the ECU.  Such a device presents a low-load input for connecting the external sensor and then produces a higher drive output for connecting to the ECU's input. ​ The following schematic can be used to build this device.

 Note that this is not necessarily an easy thing to do.  The op-amp part referenced in that diagram is extremely small and difficult to work with if you're not familiar with SMT techniques or have access to appropriate equipment.  ​ Note that this is not necessarily an easy thing to do.  The op-amp part referenced in that diagram is extremely small and difficult to work with if you're not familiar with SMT techniques or have access to appropriate equipment.  ​

 If you can't wait and working with a SOT23-5 package is just too small for you, then consider this circuit/​chip instead. ​ It's a bit easier to work with. If you can't wait and working with a SOT23-5 package is just too small for you, then consider this circuit/​chip instead. ​ It's a bit easier to work with.
